Which book cover do you like?
I like #2. But the other posts suggest I am in the minority. Again!
#2 for sure!
Number 2 is more open and eye catching, although you may want to clarify the relationship between the 2 drawings on the cover.
#2 gets my vote as most effective, because the subtitle stands out to tell you "what's in the tin". I like #1 better visually, but the subtitle gets lost.
#1 looks the best!
#2 - the other one looks too much like a medieval historical book to me...
#2 would catch my eye and peak interest...who can resist a dapper pug?
#2 Especially if your homeboy and homedog dialogs feature throughout the book. And this is not the feedback you asked for but if they had oppositional quotes under their portraits I think that would really hit it home.
My vote is #2
2 gets my vote - more inviting
